Do you REALLY have a valid reason to disable it, or is it just that you don't want Microsoft controlling you? You can always leave it and set some other browser to be the default and set Adobe Reader DC to be the default program for PDF files. Then delete shortcuts for Edge from the Desktop and Taskbar. It's always a good idea to have a second or even third browser available in case one gets infected or otherwise messed up.
I have nothing against third-party uninstallers when used for third-party programs like junkware. I am leery of using the third party uninstallers for any Microsoft apps or any antivirus apps because these may be very tightly integrated with the operating system.
Behind every good computer... is a jumble of wires 'n stuff.
Thanks Martin for your reply. I'm back after being released from hospital from my respiratory issues. Yes, it annoys th hell out of me that Win10 is even more self-serving for MS that previous versions. Of course I've had multiple browsers for a long time in the event of problem with the default Opera. I don't want to muck up the system with workarounds anymore, so I'll forget Edge and move on.
